Abstract

Researchers are devoted to developing dielectric elastomers (DEs) with excellent electromechanical properties as an artificial muscle material. The authors report a new class of semi-interpenetrating network (semi-IPN) composites that contains siloxane-modified linear polyurethane (PU) and silicone rubber through reasonable design of polymer structure. The organic-filler copper phthalocyanine (CuPc) is chemically grafted into the semi-interpenetrating network as a cross-linking point and exhibits excellent dispersibility in the matrix. The various properties of the obtained composite films are also evaluated. The dielectric constant (8.65 at 1 kHz) and maximum actuation strain at 30 MV m−1 (5.32%) are significantly higher than those of semi-IPN composites.

通过将酞菁铜化学接枝到硅氧烷改性聚氨酯上并与硅氧烷硅橡胶互穿作为复合致动器材料来增强机电性能
国家自然科学基金,授予/奖号:519730801903100摘要研究人员致力于开发具有优异机电性能的介电弹性体(DE)作为人工肌肉材料。作者通过对聚合物结构的合理设计,报道了一类新型的半互穿网络(semi-IPN)复合材料,该复合材料含有硅氧烷改性的线性聚氨酯(PU)和硅橡胶。有机填料酞菁铜(CuPc)被化学接枝到半互穿网络中作为交联点,并在基体中表现出优异的分散性。并对所得复合膜的各种性能进行了评价。介电常数(1 kHz时为8.65)和30 MV m时的最大致动应变(5.32%)显著高于半互穿网络复合材料。
